Abstract

The paper deals with an efficiency estimation of automated mechanical transmission at off-line simulation stage.

The simulation model of the vehicle with an automated power unit for gear change control strategy research is developed.

The complex mathematical description of the analysis scheme is given. It allows adequately react to structure reorganization and parameters change of dynamic system at an application of external disturbances from the road and the driver.

The distinctive feature of created software is opportunity of real-time modeling. This decision enables to estimate automated mechanical transmission operation at a wide spectrum of the driver actions.

The experiment on driving simulation of the heavy truck with GCW 40000 kg on a road climb is carried out. The estimated values of driving on a route such as average speed, fuel consumption and truck specific productivity are compared during gear changes in automatic and command modes.

The conclusions about efficiency of analyzing gear change control strategy are made. The perfecting strategy of automated mechanical transmission controlling algorithms is offered.
